Mining Program Help

I am having a strange issue with my mining program. It loops, and I can't figure out why.
Here's the code: http://pastebin.com/eaA69ppk

what do you mean with it loops?

Also, you don't need to have a local before every time you use a variable, actually, if you are inside a block(inside an if statement, a for loop, or anything really that is closed with an end.), the variable will be set to only that block if you use locals, and it will be what it was before that block in the rest of the code. also, use read() rather than io.read()

As well,

local mrad = io.read()
local mrad = tonumber(mrad)
local mrad = math.floor(mrad)

is very many lines, you can actually use functions inside functions. so that could very well be

local mrad = math.floor(tonumber(read()))

I'm not entirely sure that I get you right, but I think you're wrong. Everything declared without local will be accessible from anywhere in the same environment. It's precisely the keyword 'local' that declares them to their scope and makes them only accessible from the code block they were declared in.

yeah that's what I ment, was I unclear about it? Then I'm sorry, just read what Orwell said @OP for a better explanation

environment ~= code block. Didn't you say that non-local variables are limited to the if/while/for block they were declared in?

You guys are talking about:

if os.getComputerLabel() == nil then
  local turtleName = ("number " .. os.getComputerID())
else
  local turtleName = os.getComputerLabel()
end

Right?

Yeah, that doesn't do anything.

The program has a while loop. It loops. It looks like it's supposed to loop.

I was rather talking about what Doyle said about globals being limited to the scope of conditionals and loops. I don't really get what he's saying there. As for the local variables in the conditional, yes that's wrong, as Doyle pointed out earlier.

I ment that locals in a block will only be the value you assign them in that block, so

local a = "outside"
for i = 1,1 do
   local a = "inside"
end
print(a)

would print "outside" even though it was assigned inside latest in the code, because the place it was assigned "inside" had a local, and so, when the block ended, that local variable was gone.

And yes, I see my explanation was bad. edited it abit, but it might still be bad, so just refer to this one.
Thanks for pointing it out Orwell, bad explanations can teach bad things

Aight, no problem, I see now that we're on the same page. :)/> Good example btw.

Sorry about not being more specific; I was brain-tired and wasn't thinking right.

I have the two bottom-most sections of code set to repeat the basic mining functions with increasing height and width by adding one to the variable it plugs into the functions. But it keeps on getting stuck mining an eight block area; it keeps on mining radius one, height one. I don't understand why the last two variables are not being adjusted.

I also did understand the above discussion, and adjusted the in-game code accordingly.

Are you sure you removed all scoped in locals? because the one that we see on pastebin local chei = chei + 1 is what's making it not work

Herp derp. Forgot to save changes. It works now. Thanks!
